An attenuator decreases (attenuates) the level of the incident signal by a specified, sometimes adjustable amount.

Common uses for attenuators include limiting signal strength, buffering components, or adjusting power levels

An attenuator is the opposite of an amplifier. An attenuator is used for reducing the power of a signal. An attenuator is able to do this without modifying the waveform of the signal.

different types of material used in attenuator

An attenuator is an electronic device that reduces the amplitude or power of a signal without appreciably distorting its waveform. attenuator just decrease its amplitude and the attenuator you can take it as a opposite of amplifier. Amplifier just modifies the input signal gives amplified output signal
